9 − 3 ÷ 1/3 + 1 = ?

I was having a discussion with my friends about Maths and what we learnt and i remember that fraction divisions were confusing at first and I had struggled to understand how to work them out. I gave an example to one of my friends of the equation above and he said 9 and then I gave the same equation to my other friend and he said 1.

What is the correct answer and how do people work it out?

30 + 50 × 3 = ?

Please don't be like a lot of people all over the internet and some friends i have spoken to. I asked them to solve this equation and yes you guessed it. This is how they solved it

30+50=80
80 X 3=240

No. Please use order of operations when solving these equations.

In this equation multiplication comes first and then addition comes second.

50 X 3= 150
30+150= 180

If they're brackets solve them first, then do division, multiplication, addition and subtraction.

If there are any equations you have issues solving please comment and we can educate each other so no one makes mistakes like this again.

Imagine you are on a live game show. The host shows you 3 closed doors.

• Behind one door is a brand new sports car.
• Behind the other two doors are literal goats.

You point to Door Number 1.

Before opening it, the host (who knows exactly what is behind every door) stops you. He opens Door Number 3 instead, revealing a goat.

There are now only two closed doors left: Door 1 and Door 2.

The host looks at you and offers a choice: "Do you want to stick with your original guess (Door 1), or do you want to switch your answer to Door 2?"

The Debate: Does switching your door actually change your mathematical odds of winning the car, or is it a pure 50/50 coin toss regardless?

Settle it in the comments. Would you STAY or SWITCH?
